TRANSCRIPT
Plate tectonics
Midocean ridge is an example of this type of fault?
Transform Fault
More dense crust is pushed under less dense crust.
Subduction
Topmost part of the Earth
Lithosphere
Plate boundaries that come together.
Convergent boundaries
Movement of air within the atmosphere due to density.
Convection Currents
The Ring of Fire is around the boundary of this plate?
Pacific Plate
The theory that links continental drift and ocean-floor spreading together.
Plate Tectonics
Supporting evidence for ocean-floor spreading.
Magnetic striping
Rock aging
Cores from deep-sea drilling
Plate boundary where one plate slides past one another plate.
Strike-slip boundary
What is the V-shaped valley?
Trenches
World’s largest mountain chain is located here
Midocean Ridges
Alfred Wegener’s theory.
Theory of Continental Drift
Plate boundaries that move apart.
Divergent boundaries
Used to map midocean ridges.
Sonar
Means all of Earth.
Pangaea
Provides the framework for understanding landforms.
Theory of Plate Tectonics
When two continental plates collide with the same density, ______ plates
is subducted.
Neither

Glaciers
________ records showed evidence that Pangaea existed.
Fossil
Name the Lithospheric plates.
